This paper presents a finite difference solution for 2D, low Reynolds number,
unsteady flow around and heat transfer from a stationary circular cylinder placed in a uniform
flow. The fluid is assumed to be incompressible and of constant property. The governing
equations are the Navier-Stokes equations, the continuity equation, a Poisson equation for
pressure and the energy equation. The temperature of the cylinder wall is kept constant
and the viscous energy dissipation term is neglected in the energy equation. The computed
Strouhal numbers, time-mean drag and base pressure coefficients, as well as the average
Nusselt numbers compare well with existing experimental results.
